MEASURING DEVICE FOR COLLAPSIBLE TUBES.

Application filed January 8, 1921.

To all whom it may concern Be it known that I, FRANK L. Dyan, a citizen of the United States, and residing at Montclair, county of Essex, State of New Jersey, have invented a new and Improved Measuring Device for Collapsible Tubes, of which the following is a full, clear, and exact description.

My invention relates to an improved measuring device fon collapsible tubes 1ntended principally for containing pastes such as tooth-paste, shaving-cream, etc., and my object is to provide an improved attachment adapted to be temporarily secured to the collapsible tube and by which the contents of the tube may be ejected therefrom in measured quantities. In this way waste of such contents may be reduced since 111 the operation of these collapsible'tubes a greater quantity of the paste is usually e ected than is really necessary or desirable.

In order that the invention may be better understood, attention is called to the accompanying drawing forming a part of this specification, and in which:

Fig. l is a sectional view of the upper portion of a collapsible tube on an enlarged scale showing my improved measurlng devi'c; in its preferred form applied thereto; an

Fig. 2 is a side elevation of the same showing the upper part of the measuring dev ce broken away, and suggesting the interior construction by dotted lines.

The collapsible tube 1 is of ordinary construction, being provided with a threaded neck 2 having a passage 3 therein through which the contents of the tube are ejected by compressing the body of the same as Wlll be understood.

Secured onto the neck 2 is a tubular body 4: having a passage 5 in line with and. as a continuation of the passage 3. The tubular body 4 is formed with a flange 6 as shown, in which is a hole 7. Mounted on the tubular body 4 is a tube 8, which snugly fits the tubular body with a little friction whereby the tube maybe turned with respect to the tubular body, but will normally remain in the position to which it is moved in operation. The tube is formed with a slot 9 in which a pin 10 engages, said pin being carried by the tubular body 4, so as to limit the turning movement of the tube on-the tubu lar bod The tube is formed with a hole 11 adapte to be brought into line with the Serial No. 435,972.

hole 7 when the tube is turned to one of its extreme positions and thus open communication with the interior of the measuring device; \Vhen the tube is moved to its other extreme position these holes will be out of line, thus closing communication with the interior of the measuring device.

Mounted within the tube 8 is a plunger 12 fitting the tube quite snu 1y and movable longitudinally therein. %The plunger is formed with an extension 13 pro ecting above the end of the tube 8 and that end of the tube is crim ed inwardly, as at 14, to limit the outward movement of the plunger. ()n its'other end the plunger is formed with a projection 15, entering more or less snugly the space enclosed by the flange 6, so as to eject substantially all the contents of the measuring device, as will be understood.

In operation, the parts are in the position shown in Figs. 1 and 2, the two holes 7 and 11 being out of line. The tube is squeezed to eject the astethrough the passages 3 and 5, and will orce the plunger outwards to the limit of its movement, and thus secure a measured quantity of the paste within the device. -The tube 8 is now turned until the holes 7 and 11 are in line, whereupon the plunger is pressed inwards forcing the measured quantity of the paste out through the holes 7 and 11. When the contents of the tube are exhausted, the measuring device may be applied to a new tube.

Having now described my invention, what I claim as new therein and desire to secure by Letters Patent, is: a

1. A measuring device for attachment to a colla sible tube comprising a tubular body w ich screws upon the neck of the tube, a tube rotatably mounted on said tubular body and having a discharge opening, and a plunger in the rotatable tube, substantially as set forth.

2. A measuring device for attachment to a collapsible tube comprising a tubular body which screws upon the neck of the tube and having a discharge opening, a tube rotatably mounted on said tubular body and having a discharge opening adapted to be brought into and out of line with the discharge opening in the tubular body, and a plunger in the rotatable tube, substantially as set forth.

3. A measuring device for use in connection with a collapsible tube containing a paste-like material and consisting of a tubudischarge opening therein, means or opemn and closing the discharge opening and a p unger movable longitudinally with respect to the tubular body whereby when said opening is closed the pastelike material from the collapsible tube may be forced into the tubular body to move the plunger outwardly, and when said openingis opened the reverse movement of sai plunger will discharge a prescribed amount of material through said opening, substantially as set forth.

a. The combination with a collapsible tube, of a tubular body cooperating with the neck of the tube, a plunger in said tubular biody and moved longitudinally therein by t e the tubular body, a discharge opening from lar bod having a substantially as set ejection of the contents of the tube into the tubular body and means for opening said discharge opening, whereby the reverse movement of said plunger will eject the measured amount from the tubular body,

forth.

5. The combination with a collapsible tube, of a flanged tubular, body cooperating with the'neck of the tube, a tube rotatably mounted on said tubular body, discharge openings in the flange and rotatable tube, and a plunger in the rotatable tube, substantially as set forth.
